[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The municipal concrete road resonance stone crushing device and the rapid repair method drive the reciprocating screw and the first synchronous pulley to rotate through the output end of the servo motor. The reciprocating screw rotates through the screw hole to drive the fixed plate to slide up and down in the moving groove through the moving block. When sliding, the vertical rod moves along with the cross rod and the connecting groove. When the first synchronous pulley rotates, the second synchronous pulley and the vertical rod rotate together through the tight belt. When the second synchronous pulley rotates, the two ball bearings rotate together with it, and the second synchronous pulley is limited to prevent the position of the second synchronous pulley from changing when the vertical rod moves, so that it cannot follow the first synchronous pulley. The step pulley rotates together, and the square plate is movably connected to the vertical rod through the stabilizing hole, which can improve the stability when the vertical rod moves and rotates, and then the fixed plate and multiple crushing teeth can be rotated up and down to crush the concrete road, thereby preventing the concrete road from being unable to reach the required depth when being crushed, and facilitating the crushing teeth to move out of the entered concrete road. Moreover, multiple crushing teeth with different angles are convenient for crushing a certain part of the concrete road while contacting and crushing the adjacent parts at the same time, which can increase the area of ​​the device when crushing a certain part of the concrete road.

[0021] 2. The resonance stone crushing device and quick repair method for municipal concrete roads use a vacuum cleaner to generate suction on four dust extraction boxes through four dust inlet pipes to extract the dust generated by the crushing. When vacuuming, the filter can filter and block the external stones to prevent the stones from entering and causing unnecessary damage to the vacuum cleaner and the dust extraction box. The dust enters the dust extraction box through the mesh of the filter and enters the dust delivery pipe through the dust inlet pipe and then is sent to the water tank. During suction, the rotation generated by the meshing of the driven gear and the driving gear drives the vacuum cleaner to rotate on the outer ring of the dust delivery pipe through the bearing. During rotation, the dust inlet pipe and the dust extraction box rotate together, and then the dust generated when the concrete road is crushed can be subjected to a rotating dust suction treatment without dead angles, thereby improving the dust removal effect of the device and preventing a large amount of dust generated by crushing from causing harm to the operator's body.

[0022] 3. The resonance gravel crushing device and quick repair method for the municipal concrete road, by pulling the handle upwards to drive the cover plate to rotate together through the hinge to open the water filling tank, fill the water source into the water tank, and at the same time the water tank is loaded with the sucked dust, when the wind force generated in the dust delivery pipe by the vacuum cleaner causes the dust to be sucked into the water tank, the internal water will produce a lot of fluctuations, and when the fluctuation occurs, the water will produce impact force, and after the impact force is generated, the shaft will rotate at the bottom of the long board through the bearing, and at the same time, multiple stirring blades will rotate to stir and mix the water and dust for centralized dust reduction and collection, so that they can quickly contact and merge with the water in the water tank to prevent diffusion. After collecting to a certain extent, hold the pulling ring and pull it outward to drive the water tank to slide synchronously in the slide groove through the slider and move out of the shell, which can be convenient for the operator to centrally process the dust.

[0038] Furthermore, a filter screen 31 is fixedly connected to one side of the dust extraction box 30, and the four dust extraction boxes 30 are all set at a forty-five degree angle. Through the set filter screen 31, the gravel can be filtered when the dust generated by the broken concrete pavement is sucked, thereby preventing the gravel from being sucked in along with the dust and causing damage to the dust extraction box 30 and the dust extractor 28.

[0039] Further, the processing assembly includes a shell 32 fixedly connected to the right side of the top of the bottom plate 1, the inner cavity of the shell 32 is provided with a water tank 33, the top of the shell 32 is provided with a water injection groove 34, the inside of the water injection groove 34 is rotatably connected to a cover plate 35 through a hinge, the top of the cover plate 35 is fixedly connected to a handle 36, the inner wall of the shell 32 is provided with a slide groove 37 on both sides, the two sides of the water tank 33 are fixedly connected with a slider 38 adapted to the slide groove 37, the right side of the water tank 33 is fixedly connected with a pull ring 39, and the water tank 33 is provided with a pull ring 39. 3 is fixedly connected to the inner wall of the housing 3, and the bottom of the long plate 40 is rotatably connected to the shaft 41 through a bearing.

Through the provided processing assembly, it is convenient for the operator to send the dust generated during the crushing into the water tank 33 for stirring and mixing with water for centralized dust reduction collection, so that it can quickly contact and fuse with the water in the water tank 33 to prevent diffusion.

[0040] Working principle: during crushing, the reciprocating screw 10 and the first synchronous pulley 13 are driven to rotate through the output end of the servo motor 9. The reciprocating screw 10 rotates through the screw hole 12 to drive the fixed plate 11 to slide up and down in the moving groove 8 through the moving block 43. When sliding, the vertical rod 14 moves along with the cross rod 17 and the connecting groove 15, and when the first synchronous pulley 13 rotates, the second synchronous pulley 16 and the vertical rod 14 are rotated together through the tightening belt 19. When the second synchronous pulley 16 rotates, the two ball bearings 24 rotate together with it, and the second synchronous pulley 16 is limited to prevent the position of the second synchronous pulley 16 from changing along with the vertical rod 14 when the vertical rod 14 moves, resulting in the inability to follow The first synchronous pulley 13 rotates together, and at the same time, the square plate 6 is movably connected to the vertical rod 14 through the stabilizing hole 22, which can improve the stability when the vertical rod 14 moves and rotates, and then the fixed plate 20 and the multiple crushing teeth 21 can be rotated up and down to crush the concrete road together, thereby preventing the concrete road from failing to reach the required depth when being crushed, and facilitating the crushing teeth 21 to move out of the entered concrete road. Moreover, the multiple crushing teeth 21 with different angles are convenient for simultaneously contacting and crushing adjacent parts when crushing a certain part of the concrete road, which can increase the area of ​​the device when crushing a certain part of the concrete road;

[0041] During dust removal, the dust collector 28 generates suction force on the four dust extraction boxes 30 through the four dust inlet pipes 29 to extract the dust generated by the crushing. During dust extraction, the filter screen 31 can filter and block the external stones to prevent the stones from entering together and causing unnecessary damage to the dust collector 28 and the dust extraction box 30. The dust enters the dust extraction box 30 through the mesh of the filter screen 31, enters the dust delivery pipe 27 through the dust inlet pipe 29, and is then sent to the water tank 33. During suction, the rotation generated by the meshing of the driven gear 44 and the driving gear 25 drives the dust collector 28 to rotate on the outer ring of the dust delivery pipe 27 through the bearing. During rotation, the dust inlet pipe 29 and the dust extraction box 30 rotate together, and then the dust generated during the crushing of the concrete road can be subjected to a rotating dust extraction treatment without dead angles, thereby improving the dust removal effect of the device and preventing a large amount of dust generated by crushing from causing harm to the operator's body.

[0042] During collection and processing, the handle 36 is pulled upward to drive the cover plate 35 to rotate together through the hinge to open the water filling groove 34, and water is filled into the water tank 33. At the same time, the water tank 33 is loaded with the sucked dust. When the dust is sucked into the water tank 33 by the wind force generated in the dust delivery pipe 27 by the dust extractor 28, a large amount of fluctuations will be generated in the internal water. When the fluctuation occurs, the water will generate an impact force. After the impact force is generated, the shaft 41 will rotate at the bottom of the long plate 40 through the bearing, and at the same time, the multiple stirring blades 42 will rotate to stir and mix the water and dust for centralized dust reduction and collection, so that they can quickly contact and merge with the water in the water tank 33 to prevent diffusion. After collecting to a certain extent, hold the pull ring 39 and pull it outward to drive the water tank 33 to slide synchronously in the slide groove 37 through the slider 38 and move out of the shell 32, which can facilitate the operator to centrally process the dust.
